@LM Designers We looked at a few grays but we worried they might be too much of a 'pattern', considering the pattern of the tiles on the floor. We have to choose something from Lowes, which is part of the problem. Not a ton of options, it seems.

I would take the tile to a granite shop and use one that is cream with a darker color from the tile. Granite that has movement in the design is sooo amazing. You can find granite shops that have leftovers sometimes that you can use in a bath and they will sometimes discount them.
